what role does isolation play in adaptive radiation ??
Answer:
Such exploitation of a new environment gives rise to an evolutionary pattern called adaptive radiation. Through migration, isolation, or possibly a new mutation giving rise to a brand new adaptation, a population of organisms moves into a new geographic area where that species never previously existed.

. A protease is added to a suspension of egg protein in a test-tube and kept at 37°C. After 8 minutes, the protein changes from cloudy to transparent. Which product, or products, will now be present in the test-tube
Answer:
amino acids
Explanation:
A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
The product that will be present in the test tube will be amino acids.
Protease is an enzyme that acts on protein by converting it into different
types of amino acids.
Amino acids are referred to as the building block of life and are important
nutrients in growth and replacement of worn-out tissues. The protease acts
on the protein by breaking the peptide bonds under the required
temperature.
An inadequate temperature may result in the denaturing of the enzyme
which was why the test was done at 37°C. This is the body temperature of
humans which led to the formation of amino acids which is absorbed by cells
of the body.

Red blood cells are classifed as type A or type B, based on their surface antigens. Type O
blood does not contain any antigens. The chart below shows the possible phenotypes of
each blood type.

AB
Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

Summarize the possible applications of gene knockout GMOs.
Answer:
This method involves creating a DNA construct containing the desired mutation. For knockout purposes, this typically involves a drug resistance marker in place of the desired knockout gene. ... This method then relies on the cell's own repair mechanisms to recombine the DNA construct into the existing DNA.

s=d/t
s=34m/2s
Answer:
34/2 = 17 m/s
Explanation:
Distance Covered: s = 34 m
Time in which distance covered: t = 2 s
----
Average Speed: v = Distance Covered/time taken = s/t
v = 34/2
v = 17 m/s

In self-pollination a plant has both reproductive structures and fertilizes itself with pollen. The offspring is identical to the parent. Which type of reproduction is this?
Answer:
Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place.
Explanation:
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm. Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma. The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self-fertilization.
